Deuteronomy 22:6 in the King James Version
If a bird’s nest chance to be before thee in the way in any tree, or on the ground, whether they be young ones, or eggs, and the dam sitting upon the young, or upon the eggs, thou shalt not take the dam with the young:
Context
5 A woman shall not wear men’s clothing, neither shall a man put on women’s clothing; for whoever does these things is an abomination to the LORD your God.
6 If you come across a bird’s nest on the way, in any tree or on the ground, with young ones or eggs, and the hen sitting on the young, or on the eggs, you shall not take the hen with the young.
7 You shall surely let the hen go, but the young you may take for yourself, that it may be well with you, and that you may prolong your days.
